[2-(Phenyl-diazen-yl)pyrrolato]bis(2-pyridylphen-yl)iridium(III).

ABSTRACT: In the title compound, [Ir(C(10)H(8)N(3))(C(11)H(8)N)(2)], the Ir center is octa-hedrally coordinated by the three chelating ligands, with two cyclo-metalated 2-pyridylphenyl ligands [Ir-N = 2.049?(5) and 2.030?(5)?Å; Ir-C = 2.016?(6) and 2.012?(6)?Å] and a bidentate 2-(phenyl-diazen-yl)pyrrolate ligand [Ir-N = 2.204?(5) and 2.079?(5)?Å]. The Ir-N(diazen-yl) bond is longer than the Ir-N(pyrrolate) bond. The structure is stabilized by aromatic ?-? stacking, the shortest parallel distance between ring centroids being 3.426?(8)?Å..

In the crystal, mol-ecules of the title compound are linked by O-H?O and O-H?N hydrogen bonds. One F atom of each ligand is equally disordered over two sites. The C atom of the solvent molecule is likewise disordered over two sites in a 0.589?(11):0.411?(11) ratio.

Project description:In the title compound, [Ir(C11H8N)2(C18H14N)], the IrIII ion adopts a distorted octa-hedral coordination environment defined by three C,N-chelating ligands, one stemming from a 2-(4-phenyl-5-methyl-pyridin-2-yl)phenyl ligand and two from 2-(pyridin-2-yl)phenyl ligands, arranged in a facial manner. The IrIII ion lies almost in the equatorial plane [deviation = 0.0069?(15)?Å]. In the crystal, inter-molecular ?-? stacking inter-actions, as well as inter-molecular C-H?? inter-actions, are present, leading to a three-dimensional network.
